Switch to summer blend could bring a possible spike

Just got off a call with an oil specialist, and we are speculating about the Chicago Spot’s movement today. Reports say we have switched over to summer blend, and the price is up almost 9 cents today, even in the face of the NYMEX RBOB’s almost 4 cent drop. I’ll have my numbers sometime after 6pm tonight, and I’ll give my best guess then, but for now, it’s looking good for a spike tomorrow.
